ICON V.S. 2.5 Piggyback CDCV Rear Shocks for 2004-2015 Nissan Titan, Pair

The ICON Vehicle Dynamics V.S. 2.5 Aluminum Series Piggyback/CDCV Rear Shocks are a vehicle-specific pair engineered for 2004–2015 Nissan Titan trucks running 0–1.5 inches of rear lift, delivering tuned off-road performance and composed street manners from a single shock design. The 2.5-inch aluminum body, piggyback reservoir, and externally adjustable CDC Valve set these apart from standard replacement shocks. Two shocks are included.

Ten Levels of Compression Tuning On Demand

The ICON CDC (Compression Damping Control) Valve is an externally adjustable valve that restricts oil flow into the piggyback reservoir, producing 10 distinct levels of compression damping force. Turning a knob at the reservoir (no tools, no disassembly) lets a Titan owner dial in a softer setting for daily highway miles or a firmer setting before a loaded trail run. That range of adjustment means the shocks remain useful as the truck's role changes, rather than forcing a compromise between ride comfort and off-road control.

Internal Bump Zone Prevents Harsh Bottom-Outs

A 6061 billet aluminum manifold positioned a few inches below the top cap creates what ICON calls an internal Bump Zone. As the shock approaches full compression, this zone adds approximately 20% more damping force, progressively resisting the final travel rather than slamming into a hard stop. For a Titan carrying a load or landing a drop-off at speed, that progressive resistance translates to a controlled, predictable feel rather than a jarring impact through the cab.

Built to Last and Be Rebuilt

The shock body is a one-piece impact-extruded 6061 aluminum cylinder, corrosion-resistant and consistently finished. The 7/8-inch shock shaft is induction hardened and chrome plated for durability against debris and side loading. PTFE-lined spherical bearings handle articulation without binding. Premium 5-weight shock oil maintains consistent damping across a wide temperature range, and nitrogen charging keeps the monotube design cavitation-free. Both shocks are 100% rebuildable and 100% revalveable, so a future revalve or seal replacement extends their service life rather than requiring full replacement.

Features

• CDC Valve: 10 levels of externally adjustable compression damping, no tools required
• Internal Bump Zone: 6061 billet aluminum manifold adds ~20% damping force near full compression
• Piggyback Reservoir: improves heat dissipation to reduce shock fade during sustained off-road use
• 7/8-inch Shaft: induction hardened, chrome-plated for durability and corrosion resistance
• Rebuildable and Revalveable: 100% serviceable; vehicle-specific valving and length from the factory
• Application-Specific Hardware: PTFE-lined spherical bearings and fitment-matched mounting hardware included

Specifications

Who This Is For and Isn't

These shocks suit 2004–2015 Nissan Titan owners running stock rear height or up to 1.5 inches of rear lift who want externally adjustable compression damping and improved off-road control without sacrificing daily drivability.

These shocks do not fit Titan configurations with more than 1.5 inches of rear lift, and they are not compatible with other makes or models. Owners seeking a more user-defined tune with high-speed and low-speed bypass circuits should consider ICON's Omega Series bypass shocks instead.

Common Questions

What does the CDC Valve actually adjust?

The CDC (Compression Damping Control) Valve on these ICON V.S. 2.5 rear shocks is an externally adjustable knob on the piggyback reservoir that restricts oil flow, producing 10 distinct levels of compression damping force. Turning it requires no tools and no removal of the shock from the vehicle.

How much rear lift do these shocks support?

The ICON V.S. 2.5 Piggyback/CDCV Rear Shocks for the 2004–2015 Nissan Titan are valved and dimensioned for 0 to 1.5 inches of rear lift. Running more lift than that falls outside the intended fitment range for this pair.

Are these shocks rebuildable if they wear out?

Yes. Both shocks in this pair are 100% rebuildable and 100% revalveable. Seals, oil, and valving can be serviced or changed by a qualified shop, extending the usable life of the shocks rather than requiring full replacement when they eventually wear.

What is the Bump Zone and why does it matter?

The internal Bump Zone in these ICON V.S. 2.5 shocks is created by a 6061 billet aluminum manifold near the top of the shock body. As the shock nears full compression, the Bump Zone increases damping force by approximately 20%, providing a progressive resistance that helps prevent harsh bottom-outs during high-velocity compression events such as landing jumps or hitting sharp trail obstacles.

Is a Prop 65 warning associated with this product?

Yes. These ICON V.S. 2.5 Rear Shocks carry a California Proposition 65 warning: this product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm.
